Embodiment 1

[0067] Embodiment 1 also discloses a construction method of an assembled composite subgrade retaining wall, such as Figure 9 shown, including the following steps:

[0068] S1. Construction preparations, including the following:

[0069] S1.1. Conduct a comprehensive safety technical disclosure to the construction personnel before the slope protection construction, and conduct a comprehensive inspection before the mechanical operation to ensure construction safety.

[0070] S1.2. During construction, first remove debris and obstacles within the construction range of roads and retaining walls, take drainage and drainage measures, and level the construction site and construction access roads. Various temporary facilities, such as lighting and safety facilities, should be ready.

[0071] S1.3. Combining design drawings and construction plans, formulate work plans for construction machinery and construction personnel.

[0072] S2. Setting-out measurement: use the total station ...

Embodiment 2

[0086] Embodiment 2, on the basis of Embodiment 1, the following settings are added, such as Figure 11 As shown, a first steel rod 51 and a second steel rod 52 are vertically pierced through the cavity of the vertical channel steel 13, wherein the outer wall of the first steel rod 51 abuts against the shaft center of the vertical channel steel 13 away from the connecting column 3 and the outer wall of the first steel rod 51 also abuts against the part of the outer wall of the steel strand 4 that is away from the axis of the connecting column 3 .

[0087] Such as Figure 11 , Figure 12 As shown, the edge of the side plate of the vertical channel steel 13 is integrally formed with a flange 132, the flange 132 is located at the inner right angle of the positioning groove 31, and the outer wall of the second steel rod 52 abuts against the flange 132 and the vertical channel steel 13 on the inner wall of the inner right angle formed by the side panels. The second steel rod 52 ...

Abstract

The invention relates to an assembly type composite roadbed retaining wall and a construction method thereof. The assembly type composite roadbed retaining wall comprises a plurality of retaining structures and foundation piles arranged in an anchoring mode, each retaining structure comprises a fixing frame, and the fixing frames are filled with block stones; a connecting column is fixed to a foundation pile, the plurality of retaining structures are arranged around the same connecting column, and the retaining structures and the connecting column are fixedly arranged. According to the assembly type composite roadbed retaining wall and the construction method thereof, a steel-stone composite soil retaining structure is arranged, the structure is built in a group filling stone filling mode, wet operation is not needed, the construction period can be shortened to a great extent, environmental protection and material saving are achieved, and pollution to the surrounding environment is reduced; and the self-weight and the anchoring force are large, so that the bearing effect on a roadbed soil body can be effectively ensured.

Description

technical field [0001] The present application relates to the field of roadbed retaining wall construction, in particular to an assembled composite roadbed retaining wall and a construction method thereof. Background technique [0002] With the continuous development of highway construction, in highway engineering construction, in order to meet the safety and stability of the highway, retaining walls are often set up on both sides of the highway subgrade. [0003] The construction technology of the existing reinforced concrete retaining wall includes the following steps: S1, excavating the foundation groove along the edge of the slope bottom of the high fill slope; S2, laying a gravel cushion to the bottom of the groove, and ramming the foundation soil; S3 , Prefabricate the foundation reinforcement in the foundation groove, and pour the foundation concrete in the formwork; S4, after the foundation concrete reaches a certain strength, install the vertical wall reinforcement ...
